From the Joint with the ring the wires extend outwardly in the plane oi the -ring 22 and to the vertical planes oi the wires 23 and 24 in which planes they extend up- "wardly tangentially to these wires. The wires "28 are secured at the points oi'engagement with the wires 22,23 and 24 in any suitable manner, as by spot welding. x Secured to thewires 23 and 24 are a plurality oi" handles 28. As shown, there are tour at these 10 members, one being located at each comer of, the rack. Each handle as shown comprises a U-shaped portion astride the associated comer of the rack and comprising legs 2la' arranged in vertical planes tangentially to the wires 23 and 24, to which they are secured in any suitable' manner, as by spotwelding. Thes'e legs, as shown, extend somewhat above, the plane passed through the wire 24, and each associated pair are joined'at their upper ends by substantially horizontal portions 28b completing the U.

The handle members 28 also-serve to support r a ring member 20 having a diameter somewhat larger than the diameteroi the ring 22 and arranged substantially concentrically with it. The ring 30, as shown, is supported in a plane parallel to'the ring 22 and elevated with respect to it by m'eans oi' the members 28 which are provided with horizontal portions 28c (Figs. 2 and 4) arranged substantially in the plane'ot the ring 22.

The ring 22 is secured to. the ring 22 and supported by means of a plurality oi brackets 22. These brackets are spacedicir cumrerentially at substantially uniiorm'intervals and together withxthe rings 22 and 32 dehire the compartment. 20; This compartment, as shown (Fig. ,2) is sub-divided bythe brackets 22 into a plurality of compartments or chambers 34(Fis.'2). 3:- w j i Each bracket 22 in'iront; vertical elevation has an inverted elongated torted U in Fig. '5.- Similarly in plan, -a' distorted U-sha'peas shown in Fig, 2. In this casc,---however, the" u is i'oreshortened. i

The bottom portions 82a '01 the vertical legs of each bracket 'straight leg portions ad and m.

of the tray Ii.

minates in a substantially straight portion lib arranged at an angle to the portion "a, as shown in Figs. 2, 4 and 5 and which terminates in the bend 32c of-sthe vertical U at a point somewhat in advance of the legs 31a in the counter-clockwise direction. *The bend 13c is connected with the inner leg 33a by means of two substantially 33d adjacent the bend is formed at an acute angle with the portion 33b of the outer leg, while the portion 33c joining the portion ad to the portion Siais arranged at a somewhat greater angle with the portion 33b, as clearly shown in Figs. 2 and 5.

The points of attachment of the inner mem bers a with the ring" and of the outer members 23 with the ring 22 of successive brackets are spaced in radial lines substantially l5 apart,

while the point of attachment between the inner leg 32a of each bracket with the inner ring 32 lies in a radial line approximately l5-1'7 in advance of the radial line passed through the point of attachmentof the corresponding outer leg 33a with the ring 22. These members, as shown (Fig. 2) are so arranged that the leg portions 83a lie in lines substantially tangentially to theinner ring 32.

It will be observed by reason of the foregoing construction that the brackets '32 slope away;

from their points of attachment to the rings 22 and 32 in a counter-clockwise direction, and further, are so arranged that they define compartments having elevation and plan sections approximating the cross"section of a comparatively large shallow circulate plate. Further, it will. beobserved that the brackets support plates and the like with their fiat surfaces inclined at an angle to the vertical. in a counter-clockwise direction and in planes arranged substantially tangentially to the ring member 22. a l

The outer wall of the outer compartment2 l, as, shown, is defined by the horizontal wires 23 and 24, and the vertical portions of the wires 25, 26, 2B and Bi; the bottom wall of this compartment is defined by the horizontal portions of these wires and by the elevated ring member an; and the inner walls are defined by the outer legs of the brackets 33. This compartment 2i can be used conveniently to support dishes such as soup bowls, plates and serving dishes, the dishes being supported on anend or edge and retained by the elevated ring 20.

The entire bottom surface of the tray II is covered by means of a screen member 40 formed of wires woven together in mesh form, as clearly shown in Figs. 3 and 4. This screen, as shown, has a substantially square shape to conform to the contour of the tray II. The screen 40, as shown, is secured to a peripheral binding member I, preferably formed of rubber. This member ll is provided with a number of clips 42 which serve to secure the screen-to the under surface These clip members 42. are arranged to grip the wire portions 280 at each corher of the rack and the wire portions 25 substantially mid-way of the length of the sides ofthe wires 23 and 24. v

The central portion 40a of the screen tapers upwardly, as shown in Fig. 4. and terminates in an opening 43 which is bounded by an inner marginal member ll, securing the edges of the I screen surrounding the" opening. This member" ll preferably willbe formed of a suitable resilient.

material, such as rubber. The aperture 43 is provided to accommodate the spray device II The portion peller l6.

whereby the lower rack may be positioned within the vat without interference with-the spray device. The screen 40 functions as a bottom wall for the compartments 2! and 2i of the tray ll.

Supported above the screen I. in an open-work compartment 44 adapted to be fitted over and about the spray device It. This compartment is utilized to receive silverware and the like.

It will be observed in view of the foregoing con-' struction that I have provided a lower rack for a dishwashing vat arranged to receive a number a be substantially directed against the-faces of the dishes. In other words, the dishes are supported in planes angularly disposed to the vertical leaning in a counter-clockwise direction,

and in planes arranged substantially tangentially with the innercircle 32 of the rack located ad- -,iacent the axis of the rack and the axis-of rotation of the impeller.

The outer compartment is relatively large and functions to receive a relativelylarge number of utensils, such as large platters, bowls, vegetable dishes, large cups, etc. It will be'understood that these bowls are placed in the chamber 2! in an inclined position with their lower edges resting against the ring and their upper edges resting against the side walls of the compartment, and preferably, with their interior surfaces exposed to the action of the water hurled by the im- The screen member 40 serves to prevent small articles such as knives, etc. from falling into the lower portion of the vat. The screen further serves to help distribute the water which is hurled upwardly by the impeller over and about the utensils supported within the rack.

The lower rack is supported on the bottom walls It in an elevated position by means of legs l8 which are secured in any suitable manner to the screen 40.

The upper rack, as shown (Fig. 1), is rectangular in plan to correspond approximately to thesinterior dimensions'cf the vat l2 so that it may be-readily inserted in and withdrawn from the vat. As shown, this upper rack comprises an outer compartment-ill, a compartment 5i embraced by the outer compartment and a third compartment 52 embraced by the compartment I The rack, as shown, is formed of a plurality of wires including three substantially closed square wires 5!, 54 and 55. The planes of'these wires. as shown, are spaced apart'at substantially equal intervals in parallel relation. These wires are secured together by means of a plurality of wires of engagement in any suitable manner, as by spot I welding; These vertica'l portions 56a at their lower ends terminate in, inwardly inclined portions 56b which extend beyond the wire 65 for a distance substantially equal to the distance (rum 4 a; wire II some wire Is and. terminating at their ends in horizontal portions 50c.

The wire portions. No of the two outer members 14 at the rear thereof project upwardly wire ll.

' may be accomplished It will be observed that the wire portions 14d somewhat above the plane containing the wire member I! and are turned inwardly upon themselves to define hinge brackets 16. These brackets 18 are hinged to the portion Bib of the wire member 6|, this portion, as shown, being provided with downwardly bent. U-shaped portions -11 to receive and secure the hinges, as clearly shown in Fig. 6.

The front portions lie of the members 14 project upwardly above the plane containing the These upwardly projecting portions terminate in portions 14d turned outwardly at right angles to the vertical portions llc, as shown in Figs. 1 and 4. The frontend portions of the two wires'liaof the member 15 are turned upwardly in a vertical direction at right'angles to the plane containing the member 15 to define portions 150 that lie in thevertical plane containing the portions 14 ofthe member 14. The upper ends-of these portions 15c terminate in horizontal portion "lld that lie substantially in the plane of the wire portions Md. The front ends of these portions lid are connected by means of a transverse portion 15c. The wire. portions Ild' are secured at their ends to the transverse portion lie as shown in Fig. 1. This by means of spot welding.

and lid define a ledge arranged in a plane parallel with the plane containing the wire II and elevated somewhat above this plane. This ledge serves as a means for supporting the front end of the tray I2. The ledge, as shown, cooperates with a stop or .abutment 1B which is secured to the front side of the intermediate wire '54 in any suitable manner as by welding.

Preferably the vertical portions 14c and lie will be braced by means oi a transverse wire 11 secured to the wiresinany suitable manner, as

by spot welding.

The inner compartment 52 is completed by a plurality of transverse wires 18, spaced at intervals longitudinally of the rack and extending across the bottom of the compartment substantially tangentially to the portions Ila of the wire" hinged at its rear end to the'wire-Blb and is provided at its front end with a ledge which cooperates with a suitable stop I8- to support the front end of the tray. This arrangement is a very important feature of my invention in. that the compartment 52 may be swung as a unit upon the hinges I! to an open position; whereby access may be had to the lower'tray I l without the necessity of removing the entire upper tray Ill. It will be observed that the compartment 52 is relatively large so that when it is open a relatively large opening is provided in the upper tray' through which the attendant can conveniently load and Y unload the lower rack II. If desired, the compartment 52 may be arranged to be removed as a unit from the upper tray I I.

It will be understood in view of the foregoing construction that the relatively deep compart- -ment ill may be used to support such flat utensils as saucers and the like in a substantially vertical position, while the intermediate compartment 5| can be utilized to support water glasses cups, small bowls, and the like at an angle to the vertirected toward the interior of the vat. The inner compartment 52 may be utilized to support water goblets, deep bowls, cups and like members in an inverted position so as to expose their inner surfaces to the action of the .water. This inner compartment 52 may be further utilizedto support bottles having relatively large mouths or openings, such as milk bottles, in an inverted position so as to expose their interior surfaces to the action of the water which is hurled upwardly. and outwardly through the vat by the impeller. For this purpose, the wires 14 and certain of the transverse wires 18, as for example the two first wires 18 positioned at the front of .cal and preferably with their inner surfaces dithe compartment, are provided with bends or curved portions 80 which taken together approximate a circle. It will'be understood that the bends 8 0 are arranged to receive the neck or similar portion of a milk bottle or the like when it is in an inverted position, the body of the bottle resting on the'wires ll, 18 defining the bends,

whereby the bottle is supported in an inverted position in the vat.

port a suitable soap or detergent container II. This container comprises a cylindrical body portion 82 over the mouth or lower end of which is provided a closure member vl3. This closure member, as shown, is secured in spaced relation with the lower edge of the member 82 by means of 'a plurality of straps 84. The member BI, as shown, is provided with a reentrant bottom which extends upwardly into the cylinder. The cylindrical portion 82, and its attached cover 83 are secured to the wires 14 of the tray 52 by means of suitable clamping members 85.

It will be observed that soap or some similar The compartment 52 is further utilized to supmaterial placed in the container normally will be to function to wash soap from the receptacle into the vat because the bottom cover 83 operates as a baflie to deflect the water issuing from the nozzles Ila from 'the container. This is an important feature in that while detergent is automatically supplied for the washing operation, it cannot be supplied duringthe rinsing operations. This is in comparatively small streams or sprays, and,

theretore, very little. it any, of the water will find 'lts way into the upper open end of the container 84: the-impeller It, however, in operating to wash 'the dishes, hurls relatively large quantities of water upwardly through the rack with considerable force so that a material'volume of the water vanes'todlre'ctthewaterin alidirectims through the upper rack I0, and hence, .to eflecta thorough cleansing action on the. utensils placed the'compartments 50, hand of the upper 5 rack and within the compartment 2| 0! the lower rack are exposed to the direct impact 01', thewater. In rinsing thedishes, it ,will bequnderstood within this ma The'dlshes supported within m is deflected from cover its 0! the vat into the that the spray device It is used. Water issuing o mouth of the container where it mixes with the from the nozzles its is thrown upwardly and 7 cups, bowls, bottles and the like soap and washes it out of the opening in the bottom or the container; 1 v t Arranged :directly above the soap container is inverted U-shaped portions iormed in the transverse members II to e tend upwardly between the middle longitu wires ll. These upturned, portions are defined by vertical sections of wire "a connected by means of transverse portions lib. The upper ends, of these portions sub-' stantially at the points or connection between the vertical wires lidand the horizontal wiresflib are joined by means of transverse wires 81. This brace functions as a guard to prevent the utensils that go in the compartment 52 irom being placed directly over the mouth oi" the container 8 I.

' Preferably all-oi the wires forming both the lower and upper trays will be covered with a so resilient ooating'i'ormed of some suitable mathe lower rack while the racks are positioned within the wit, itis merely necessary-to move the compartment 82 or the upper rack on its hinges to an open position, whereby access can 45 be had to the interior of the vat. The attendant may then load-the lower rack. 'While the com-v partment i2 is open, the attendantalso probably will plaee the silver and like utensils in the compartment llprovided for them. Then all these will be placed in the compartments of the lower'rack, while such utensils as soup plates, serving dishes, etc. will be positioned within the outercompartment 2| oithelower rack, soas to be supported by the-ring.- Small .flst dishes, such as saucers, etc. will beplaced in the-compartment II or the upper rack, while pups, small bowls, etc will be arranged in the compartment bl with their inner surfaces exposed to the interior or the vat. Relatively deep by the compartment II.

The arrangement oi the compartmentsll'oi the lower is quite important in that,as has previously, water which is whirled andfou through the vat will impinse upon the .sides oi the dishes resting f compartments with considerable "i'fo'rce. The dishes are so. supported in. the com--.

7' partment that they serve as bailies' or deflecting a suitable brace '6, which is defined by u raised' upon the'lower rack ll. Hit beidesiredto load outwardly through the vat in streams and will cover all portions oi the. utensils located within therackslliandll..-;'

I! the dishes are allowed to remain in the vat to those in the, upper rack lliwiil first go be removed, and then the compartment 52 will be opened sothat thosein the lower rack II can be removed 0! course, if desired .both racks may be removed while loaded, the dishesthereai'terbeingremoved. a Y

While I have shown a particular'embodiment 01' my invention,'it will be understood, oi course, that I do not wish to be limited thereto since many modifications may be made, andI therei'ore contemplate 'by the appended claims to cover any such modifications as iallwithinthe true spirit and scope of my invention.
